2. Silicon - Wikipedia

   en.wikipedia.org/wiki/Silicon

   Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive.

3. Carbon group - Wikipedia

   en.wikipedia.org/wiki/Carbon_group

   The carbon group is a periodic table group consisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). It lies within the p-block. In modern IUPAC notation, it is called group 14. In the field of semiconductor physics, it is still universally called group IV.

   It belongs to group 14 of the periodic table. [13] Carbon makes up about 0.025 percent of Earth's crust. [14] Three isotopes occur naturally, 12 C and 13 C being stable, while 14 C is a radionuclide, decaying with a half-life of 5,700 years. [15] Carbon is one of the few elements known since antiquity.

7. Group (periodic table) - Wikipedia

   en.wikipedia.org/wiki/Group_(periodic_table)

   In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.
